I think you are overestimating the number of people who care about the bezel. I think the numbers are low because it is not a significant upgrade over the 6s or 7, tech wise.
Which I actually would argue it is... If you could look beyond the bezels for a second, pretty much everything else has been tweaked or updated... To me that's pretty damn good...
If I were to upgrade my iPhone this year I would go for an iPhone 8 Plus and not the X... The X is gorgeous but expensive, a lot of first gen stuff in it, and very hard to get... iPhone 8/8 Plus is as good as the X, just not as gorgeous and my phone is an extensive work horse, so 8 Plus is a great phone.
